About twenty years ago at EGNM I watched an Aer Lingus F50 perform a right hand orbit when on about a two mile final for RW32. The Tower controller's instruction was, "Shamrock 368, my apologies. Would you carry out a right hand orbit please.' I imagine it was requested for spacing reasons. Anyway the pilots immediately complied and their aircraft was back on final shortly. Problem solved. I don't know if anything was said between pilots and ATC on the ground afterwards. It was, by the way, a fine summer evening with good visibility.
